Zusammenfassung:A surfactant composition for use in well treatment, particularly for removing oilbased mud deposits from a well prior to cementing, comprises an alkylpolyglucoside in a solution of a mutual solvent for water and hydrocarbon. The composition can be used to formulate a chemical wash by dissolving the composition at a concentration of about 1% - 10% (e.g. 5%) by weight in water or brine.
